SIDE-REGISTER DEVICE FOR PRINTING MACHINES.

Application filed November 6, 1925, Serial No. 67,226, and in Great Britain November 24, 1924.

This invention reiates to side register devices for printing machines, of the type in which a pair of feet is reciprocated inwards and outwards transversely of a feed board, and at or near the termination of the inward travel, seize between them a sheet to be registered, and during their outward movement bring the said sheet into contact with the side register stops, and thereafter slide out of engagement with that sheet and move back to starting position.

The object of the invention is to provide an improved constructionwhich shall ensure a more uniformly distributed grip being obtained on the sheet so that the latter shall be less liable to damage or defacement than has heretofore obtained with side register devices as heretofore constructed.

Tothis end an adjustable bracket which, as heretofore, is reciprocated transversely of the feed board, carries the upstanding stem of the upper side register foot in such a manner that said foot is yieldingly pressed rectilinear-1y downwards as by a spring acting on the stem (with a pressure which can be adjusted), and can be raised rectilinean 1y by a cam acting on a pin extending later: ally from the stem.

The invention will now be described by reference to the accompanying drawings in;

which Figure 1 is an elevation of one constructional form of the device as viewed from the feeder side of the printing machine to which it is applied; c

Figure 2 is a plan of the device, and

Figure 3 is a front elevation of the pertinent parts of the device as viewed from the underside of Figure 2.

For convenience of illustration the device is represented in Figures 2 and 3 as though it occupied a horizontal working position instead of, as it does in practice, an inclined one such as is indicated in Figure 1.

The before mentioned bracket 1.is adjustably secured, as by a split sleeve 2 and clamping screw 3, to the register tube 4 which, in the ordinary well-known manner, is longitudinally reciprocated transversely over the feed board 5. WVithin the bracket 1 is longitudinally slidable the upstanding stem 6 of the upper side-register foot 7 which normally is resiliently pressed downwards by a helical spring 8 encircling the upper reduced end of said stem and at its lower end bearing on an annular shoulder on the latter. The stem 6 and spring 8 are contained within the tubular part or barrel 1 of the bracket 1, and, at its upper end the said springbears against a screw 9 which is adjustable in the barrel for varying the pressure exerted by the spring 8 on the foot 7 The stem 6 has rigidly attached to it, a pin 10 which extends laterally through a slot or recess 1 in the lower end of the barrel 1 and at its outer end is adapted to engage with an inclined pivoted cam 11 by which it is raised antagonisticallylo the spring 8.

The cam 11 is supported by its pivot 12,

in a bracket 13 herein termed a cam bracket which is adjustable along a stationary rod 14 extending transversely over the feed board 5 and can be secured in any desired position thereon by a pinching screw 15.

The lowest position of the cam 11 is determined by a stoppin 16 fast in the cam bracket lS and against which the said cam is normally held by a spring 17 whose upper end bears against a lug 13 integral with the cam bracket.

The lower side-register foot 18 is secured to the bracket 1 and, as ordinarily, shares with the upper side-register foot 7, the

travel transversely of the feed board 5.

19 are the side registerstops out to which the respective side edges of the sheets are drawn to determine the correct side register, and 20 is a part of one of the inclined sticks on which the sheets are supported during the time-that they are drawn the feet 7, 18 outwards to the side register stops 19.

At the start of the inward travel of the two side-register feet 7, 18, theupper'foot 7, is in its lowest position resting upon the lower foot 18 as shown in Figure 3, and, at alater part of this travel, the pin 10 rides over the top ofthe cam 11 so that the foot? is raised rectilinearly so as to pass clearly over the adjacent edge of the sheet to be registered, while, at a still later stage, the pin 10 drops over-the inner end of the cam 11 and allows the upper foot 7 tobe depressed by the spring 8 on tothe sheet to grip it between said upper foot and the lower foot 18. The two feet 7, 18, thenstart on their outward travel bringing the sheet with them, and during this stage of the operation, the pin 10 passes beneath the cam 11 and tilts it about the axis of its pivot 12 without fit itself or the upper foot 7 being affected by this contact of pin and earn, the sheet eonsequently heing drawn outwards to the side register stops It), after which juncture the continued outward travel of the feet 7, 18 results only in their slippage ofi the respee tive edge oi the sheet leaving the latter in eontart with the said stops.

Having described my invention I declare that what l claim and desire to secure by Letters Patent: is:--

1. ln a side register device of the type deserihed for printing machines, the combination with upper and lower side-register feet adapted to grip hetiween them the sheets to he registered, and means for i'eci n'oeatin g in rect linear direction said Feet inwards and outwards lrtinsversely of a teed hoard, of a guide for the upper sitle-register 'loot eonstanlly peipeiulicular to the plane of the sheet to he gripped. hy which. n'iovenient: of said toot relatively to the other loot restri ted to re tilinear direction perpendicular to the plane of the sheet, and a cam adapted to more the upper sideaegister foot rectilinear-1y away from the lower one during the mutual travel ot' the feet in one direpion over the l'eed hoard and to allow the said upper tool. to travel in the reverse direction over the Feed hoard without: moving relativel to the lower one.

Q. In a side register device of the type deserlhed for printing machines, the eon'ihination with upper and lower side-register .t'eet atta ned to grip het ween them the sheets to he registered. and means for reciprocating in rectilin ar direction said ,teet inwards and outwards transversely of a feed hoard, of a guide for the upper side-register foot coustantly perpendicular to the plane of the sheet to he gripped hy whielu inoven'ient of said foot relatively to the other foot is restrieted to rectilinear direction perpendienlar to the plane of the sheet, and a cam adapted to move the upper side-register foot reetiliuearly away from the lower one during the mutual travel oi the feet in one direetion over the teed hoard and to allow the said upper :loot to travel in the reverse direction over the teed hoard without moving relatively to the lower one a spring adapted to bring the upper side-register foot into sheet-engaging relationship with the lower SllGQl-l'ttilSl'C! foot and, excepting when the cam acts on the said upper side-register fooh to maintain the latter in sueh relationship.
